What multitasking does to our brains

We all know this and have heard it hundreds of times. To work efficiently we have to single task. No multitasking.And yet, we let it slip. We end up eating lunch in front of the TV with our laptop open. We browse Twitter and Facebook, whilst sending emails, and chatting in multiple Gchat windows too. When really we should be focusing on just that one assignment, blog post, proposal or piece of code.So one thing is for sure, we are all aware multitasking different things at the same time makes us less efficient.Why the heck is it so hard to focus on just one thing then?Recently I started to develop a new work routine online, that specifically focuses on singletasking only. The results I got were amazing and I want to share more on this further down.

To understand what actually goes on in our brains and see if it all makes sense, I went ahead and found some stunning research and answers to these questions:

Why we multitask in the first place: It makes us feel good

To understand why we always fall into the habit of multitasking, when we know we shouldn’t, I found some very interesting studies. The answer is in fact quite simple:

“[People who multitask] are not being more productive — they just feel more emotionally satisfied from their work.”

This is what researcher Zhen Wang mentions in a recent study on multitasking. She mentioned that if we study with our books open, watch TV at the same time and text friends every so often, we get a great feeling of fulfillment. We are getting all these things done at once, and we feel incredibly efficient.

Unfortunately, exactly the opposite is the case. Students who engaged heavily in multitasking activities felt great, but their results were much worse than that of people who didn’t multitask.

Another problem a study found, is that multitaskers seem very efficient from the outside, so we want to be like them. We see someone who can juggle emailing, doing phone calls and writing a blogpost on the side and feel “wow”, that is incredible. I want to be able to do that too!

So very unknowingly we put a lot of pressure onto ourselves to juggle more and more tasks. When really, it only seemingly makes us more productive. The daily output as Wang found, only decreases though.

What is going on in our brains when we multitask?

The interesting part is that our brains can’t multitask at all. If we have lunch, 5 Facebook chat windows open and also try to send off an email, it isn’t that our brain focuses on all these activities at the same time.

Instead, multitasking splits the brain. It creates something researchers have called “spotlights”. So all your brain is doing is to frantically switch between the activity of eating, to writing an email, to answering chat conversations.

In the image below, you can see the different brain activities for various tasks that the brain switches between. It jumps back and forth as you focus on each task for a few seconds at a time:

What’s more is that Clifford Nass, a researcher at Stanford assumed that those who multitask heavily will nonetheless develop some other outstanding skills. He thought that they will be amazing at 1. filtering information, 2. being very fast at switching between the tasks and 3. keeping a high working memory.

“We were absolutely shocked. We all lost our bets. It turns out multitaskers are terrible at every aspect of multitasking.”

People who multitask a lot are in fact a lot worse at filtering irrelevant information and also perform significantly worse at switching between task, compared to singletaskers.

Now most studies all point towards the fact that multitasking is very bad for us. We get less productive and skills like filtering out irrelevant information decline. Personally I had the same results without ever reading the above studies before. I put some things in place, especially with working online, to win my productivity back and ban multitasking from my workflow once and for all.

How I developed a singletasking workflow online by adding a twist to well-known techniques

Before I learnt about any of the above, I had my own struggles with multitasking. I would have 2 separate email inboxes open, TweetDeck at the same time, as well as Facebook and an instant messaging tool.

The thing was that I felt very much on top of things, hitting “command + tab” all the time to check if I missed anything in one of the windows. With every tab switch it felt as my head would get bigger, whilst I would get less and less done at the same time. Both my brain and my work was rather scattered.

I had to stop this and I had to stop it immediately to work more productively on Buffer. To solve my multitasking madness, there were in fact 3 key changes I made to develop a full-on single tasking focus:

1. The single browser tab habit

One strategy I put in place is something I call singletab browsing. I would limit myself to only keep 1 browser tab open whenever I am working. That way I had to really prioritize what the most important task was that I had to work on.

To explain in some more detail. Some key tasks I am juggling are email support via our HelpScout inbox, Tweets for our @bufferapp account, blogposts for the Buffer blog here and emails from my personal inbox.

Before I would have all these things open at the same time. Now I work through them one by one. Only my HelpScout inbox is open. Then only TweetDeck is open to reply to any Tweets. Then I move on to close everything and only open Word to start writing. And finally I move to my personal email inbox, closing everything else again.

Doing this is only possible with one improvement I put in place:

2. The evening planning routine

This is my Moleskine filled withbrainstormed tasks for the day.

The second thing, that really makes my single browser tab habit possible is the evening planning routine.

Every evening, I would sit down and jot down what I would want to get done the next day. That’s a very common technique, and probably something that you have done before also. It’s a simple to do list, that you learn to keep in elementary school.There was only a slight problem with to do lists. I wouldn’t stick to them.

So I added a twist to it. Besides jotting down what I wanted to do, I would add a brief brainstorm with Joel. Doing this seemed like a small change, but made a huge difference.

When we sat down for just 10 minutes every evening, to briefly walk through the tasks of the next day, everything changed in terms of productivity. The reason was that instead of just writing tasks down, I was forced to also think through the tasks and explain them to Joel. “I want to write this article on this type of content, because of this inspiration I had. I will structure it like this..” and so forth.The to do list I jotted down didn’t change, but it felt as if I had done half the work of it all in my head already. The next day, all I had to do is look at the task and get it done.

If you keep a to do list, but rarely stick to it, try the same and find a colleague, spouse or friend to brainstorm 10 minutes every evening. You can do this for each other and frankly, it becomes a lot of fun to meet up for this quick brainstorm every day.

3. Change work location at least once a day

This is something that inevitably has made me more productive and focused on singletasking. We read many times that we have to work on building a comfortable work space to focus. What I found was this: I had to create many of them.

To regain focus after finishing one task and moving on to the next one, just spending 5 minutes as a break, getting a drink or similar didn’t work. Nor did closing the laptop for 5 minutes or standing up from my desk. I had to physically move from one place to another.

So most times, I work out of my apartment for the first half of the day, then I have a list of coffeeshops I can go to, or the lounge area in our apartment building.

I completely understand that moving around isn’t possible for everyone due to their work setup. There are some very creative workarounds some companies have come up with though, that might help you here. Valve, dubbed “The bossless company”, gives every employee a desk mounted on wheels, so they can change location every so often during the day.

Quick last fact: listening to music whilst working isn’t multitasking

In case you were wondering whether now you also have to give up listening to music to be more productive, rest assured, that isn’t the case, Stanford Professor Clifford Nass mentions:

“In the case of music, it’s a little different. We have a special part of our brain for music, so we can listen to music while we do other things.”

Personally, I am very excited to challenge my own workflows and see how I can exchange my existing routines for more effective ones. Singletasking has had one of the most powerful effects more me. This has worked both for results for Buffer and my personal projects. Of course, this only works if grouped with other habits that set you up for a successful singletasking day.

I am very curious to learn how you approach multitasking online. Do you have mechanisms in place that help you to conquer all distractions on the web? What do you do to avoid multitasking?
